I've just ordered a Shimano dynamo hub for the Bacchetta Giro20, since I'll not be using the dynamo wheel on this bike often I thought that I'd just try out the cheapish Shimano hubs to see what they're about. Ordered the DH-3D30 that is suited to 20" wheels and it is cheap at only â‚¬28 from Rose Versand UK. We'll see if I should have just stuck with a Schmidt SON 28 hub.

Noticed also that Starbike sells the same hub for â‚¬59 and you have to buy the overvoltage protection separately. Also the prices on the SON hubs has gone up. Looked at the SP hubs but what was on Ebay was only a couple of models, not the whole range, not the model I wanted. Still, the SP apparently is heavier than the cheaper Shimanos and has more drag when running the light. But then again the SP website is missing details of the 2011 versions of the hubs that are being sold on Ebay, looks like the pre-2011 models are being rebadged to other brands. Confusion that someone else can sort out.

The Son Deluxe is intended for use on bikes with small diameter wheels.

It's not clear there is a real need for wider flange spacings on small wheels.

The latest SON hub such as one I recently purchased is called the SON28 Deluxe (well by Starbikes anyway as per my invoice) and this is the wide version of it. It is not as I understand it the small wheel hub as you suggest.

With Starbike no longer selling Rohloff hubs to Australian , I wonder how long before we canno longer get acess to other items like the Son dynamo hubs due to this protection racket.What happened to free trade?

Bike24 is now selling SON gear I just found this morning, and they have DT swiss spokes as well. Looks like they are moving in on starbikes territory, now if only they could pick up their shipping game....

The page shows that the 2012 model Son 28 shares a similar rounded shape to the Son Delux, but is engraved with Son 28. It also shows that the Son Delux has engraved indentification, and the text mentions the forthcoming Son Delux Wide body.

The Son Deluxe is designed to produce sufficient output at the lower axle speeds of small wheels, and should only be used with larger diameter wheels if an LED headlight is also used, but commonsense suggests the Son 28 is the best choice for 700c wheels (particulary if you want to charge batteries). A Son 28 can be used with any size wheel. There does not appear to be a model Son 28 Delux. It's important for intending buyers to avoid confusion between the two models.

Since I am sitting here in Darwin trying to get better I thought I would investigate building up a 26"dynamo wheel for my Giant XTC 2 which gets used now and then as a touring bike. I need a second front wheel anyway for the Extrawheel Voyager so might as well make this build a dynamo.

The Giant XTC 2 has Shimano M485 hydraulic w/6″ centre-lock rotors so I just need to make sure that what I get as a dynamo hub will alllow to switch over the disc (I assume that is all I need to do).

I was thinking of getting a Shimano Deore XT DH-T785 dynamo hub Centerlock which seems the better of the Shimano options, which I will build into a Mavic XM-719 rim. Hopefully all up less than $200. Sound okay for a fairly low usage touring wheel?

Also is anything else needed to allow for a Busch & Mueller light connection?

No, IME they come with a connector for the dynohub end. My last couple of B&M lights had the wire permanently attached, so it was just a matter of snapping the connector (which is in 2 pieces and looks a bit like Lego) onto the stripped ends.

Please point me in the right direction to get an affordable but decent, (read the sweet spot) dynohub wheelset for a road bike (Malvern Star Oppy). I got some quote for $700(ish) including front and rear lights

Then its a matter of choosing spokes and rims that you want.I got mine supplied and built by wheelbuilder.com and was extremely happy with the price and service.I cant offer the build price as a comparison as my wheels are 20" 406's and I needed my spokes (cx-rays) custom shortened ($3.20 each).From memory I supplied the hubs and they made the spokes and supplied the rims.With postage my 36 spoke wheels were approx $700au for the pair.So perhaps think along the lines of $233 (hub) plus $350 Au (rim, spokes and build) delivered.Hope this helps.PS. Once you've paid the money the pain of it is over for many a year.

For a good bit less than that price you should be able to get a complete Schmidt SON28 wheel made up, complete with B&M IQ Cyo headlight and B&M Topline plus. Go to Starbike and get a quote. A friend of mine had a Shimano Alfine dynohub built into a wheel and shipped to him for something under $150.

Quite right, he did ask for the sweet spot.My example is probably the best price for the top end.At least the sites I offered should still have the best prices for the current batch of available hubs as well as you suggested, IP, ready to go wheels.

ThanksAndrew

no, you should not. That 2 dotted lego grey looking piece on the right is the connector. The 2 wires that come off the B&M headlight go into those 2 "holes", they dont really look like holes because the hole have been filled in with some sort of wax. The tech docs show how its done.

Looking at the exploded diagram wandering if only having the single set of bearings is a disadvantage. Also wandering if it is the reason any time I stand and ride (to get over a hill) I get disc rotor rub.

the only other "gotcha" I can think of is a center lock disc rotor is needed or a center lock/6 bolt adapter. I went the adapter and noticed that the actual hub did not come with a lockring, mine came with the adapter (not sure if this comes with the rotor or not). Surprisingly enough the lock ring uses the same tool as the cassette lock ring tool

Now thinking about about a build with a Supernova Infinity S dynamo hub 32H and Supernova lights for my commuter as my new winter commute starts in the dark and finishes in the dark (around two hours each way) and keeping the batteries charged up is becoming a pain. The wheel build (Mavic Open Pro 32h CD) works out at $287.45 ex http://starbike.com.

If I get the Supernova I will have a Shimano, a SON and Supernova dynamos so a chance to do a bit of comparison

I thought the same thing when I looked at the diagram for my Shimano Dynohub. After a bit of research I found out there are in fact two sets of bearings like a normal hub. Its just that Shimano don't consider them user serviceable hence no inclusion on the exploded diagram. They are serviceable but a fairly fiddly and delicate job. There is a soldered on wire that runs in a groove along the axle that exits at the plastic connector. Apparently it is easy to break the soldered connection when opening the drive side bearings up and render the whole unit kapput.
